Tbf it does look like the F150 and it's not a 'true' work truck given it's size and load capacity. It's BYD's first iteration and foreign focused product so they will learn valuable lessons from launching the product. People's negative bias against BYD will wear over time if they are able to release products people actually want.
Why they made a design that is so similar to F-150 is baffling.
Low speed limit is clearly electronically limited for safety purposes.
Payload and towing capacity is inline with the competition, not sure what the criticism is about.
Ford Ranger - 850 Kg/3400 Kg
Toyota Hilux - 940/3500
Toyota Tacoma - 760/3000
Chevy Colorado - 770/3500
Nissan Frontier - 725/2700
Maybe they are comparing to the larger F-150 because of the styling? The Shark is a little bigger than the other midsize trucks, but is definitely smaller than full-size
